'PECIFICATION forfi Ib part of Letters Patent No. 355,786l dated January 11. 1887.

Application filed February 1x 18:6. Renewed November 29, 1&6. Serial No. 220,223. (No model.)

To all 107mm/ it may con/cern.- Beit known thatI we, SETH WHITE PAINE and EDGAR S. CoMBs, citizens ot' the United States,`rcsiding at Rochester, in the county of 5 `Monroe and State ot' New York, have invented new and useful improvements in Lasting-Ma-` chines, of which the following is a specification.

ln lasting-machines of the special type to IO which our invention pertains it has been customary to employ a series of-overhanging pinchers in connection with last-supporting devices and means for turning the edges of the upper down upon the insole placed on the last. In such machines the arrangement of the pinchers above the lasting devices necessitates the employment of counterbalancing mechanism and places the pinchers in such position that they cannot readily be reached and manipulated for purposes of adjustment or otherwise. l `urthermore, in machines possessing overhanging pinchers the last and the lastingjaws, with their operating mechanism, must be placed in such apositiou that they cannot z5 be operated with facility, and when repairs or any adjustment is necessary the parts are not easily accessible.

It is the object of the present invention to provide a lasting-machine in which the pinchers are carried by a frame which moves in a horizontal plane to and from the lasting devices carried by a vertical plate on a basei'rame. Upon posts projecting from this vertical plate are mounted the means for supporting the last, thejaws for turning the edges of the upper down upon theinsole, and means for holding` the last while the longitudinallymovable pinchers are pulling upon the upper to stretch the same and allow it to be properly to seized by the lasting-jaws. Thesejaws are of a sectional construction, so that proper adjustments can be made for using the same upon different-sized lasts, and positive adjusting devices are also provided for varying the sweep or throw of the devices which actuate the jaws. Furthermore, the movable arms which hold the last against the pull of the stretching pinchers are i'ulcrumed on horizontal posts projecting from the Vertical head-plate, andy 5o are swung to and from the last by lever mechanism within easy reach of the operator. One

of these last holding-arms carries devices for holding down the boxing-strip upon the insole until such time as the upper has been properly stretched, and the jaw at the toe of the 55` last Voperates to turn down the edge of the upper when said device for holding the boxing is automatically released or pushed out of the way and placedin the proper position for the next operation. The horizontally-operating 6o stretching-pinchers are, in our present invention, mounted upon a l'rame which allows them to be brought toward the lasting devices for seizing the upper and moved in an opposite Ydirection for stretching the latter' and freeing 65 them from the upper when the lasting-jaws have properly seized the same. Pinchers of aspecial construction are employed,and novel devices are resorted to for adjusting said pinchers to suit different-sized lasts or special kinds 7C of work. Furthermore, the present machine is so constructed that the seizure ofthe upper is always insured by the act of moving the pincher-carrying frame toward the lasting devices.

The invention briefly outlined in the foregoing statement will be hereinafter more fully described, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is 8o a side elevation of a lasting-machine embodying our improvements. Fig.'2 is a horizontal longitudinal section through the line a a of Fig. l. Figs. 2tL and2l show means for connecting the main lever shaft with the tem- 55 I piet-lever. Fig. 3 represents in elevation the last-ing devioes,lastholder,andmode of mounting the same upona vertical head-plate. Fig.

Fig. (i is a detail view of a :tleXible end jaw'. Fig. 7 represents the construction of the pinchers and means for connecting the same with the carrying-frame. Fig. 8 shows the manner of adjustably holding the Shanks of said pinchers in a slotted holder. Fig. 9 is a sectional view showing said slotted holder, adjustable pincher-block, and means for locking roo the latter. Fig. 10 is adetail view of friction holding-blocks for the pinchers. Fig. 1l is a detail view of a' slide-block with posts and other devices for supporting the last and laststrip, Fig. 19 is a detail view of the toe-rest of the last. Fig. 20 is a perspective View of axed frame mounted, having fuleruried posts for the pincher-operating levers. Fig. 21 represents a movable frame cooperating with the fixed frame, and also having fulcrum-posts. Fig. 22 isa detail view of the iixed and movable frames, lever, and bar upon which the operating-rods of the pinchers are mounted.

The reference-numeral 1 designates a horizontal frame or table, which is mounted upon suitable legs, 2, and carries at one end a vertical plate, 3, which, for the sake of convenience, will hereinafter be termed the headplate.7 At the other end of the table is mounted a fixed supplementary frame consisting of topand bottom and vertical connecting-bars. This frame 4v serves as a support and guide for a movable frame or sash, 5, which carries the devices concerned in the operation of stretching the upper, asy will be hereinafter fully explained.

Referring first to the devices mounted upon the head-plate 3, which ymay be defined by the ter'm lasting mechanism, it is seen that the last is held in a' vertical position, and that the toe and heel lasting-jaws move horizontally to and from the last.

The reference-numeral 6 represents guideways formed in or upon the head-plate for the reception of movable blocks 7, carrying straight horizontally-projecting posts or arms 8 and 9, as is clearly indicated in Fig. 11. The post 8 is provided with an external screwthread, and is made hollow throughout nearly its entire length for the reception of an elongated collar, 10. rllhe latter receives a shank or pin, 11, carrying a vertical pin, 12, which moves in a horizontal slot` made in the post 8. Thelatter has an encircling sleeve, 13, through a slot in which the pin 12 projects, and this sleeve is surrounded by a..coiled spring, 14, which bears upon the pin12 and upon an adj ustable nut, 15, applied to thescrew-threaded portion of the post 8. Q By means of said nut the tension of the spring can be adjusted, and the presence ofthe collar 10 will allow the pin 11 to be projected more or less from the post 8, a set-screw, 16, being provided to hold the collar 10 in place. This pin 11, in connection with a similar one arranged in line therewith, serves to support the last, as will be hereinafter set forth. rlhe post 9 is also made hollow, and receives a screw-threaded stem, 17, the outer Figs. 14 to 18, inclu-' end of'which hasjan eye, 18, constituting the..

point of support for a lasting device. A setscrew, 19, projecting into the bore ofthe post 9 bears upon the screw-stem 17, and serves to -prevent the same from dropping ont, and a nut,` 20, is the medium for adj usting the screwstem in and out ofthe post. The slide-blocks 7 and their two posts are the same at the top and bottom of thehead-plate 3, and, as already stated, the posts 8, or rather-the pins 1l, mounted therein, carry the means for supportingthe last.

The device for supporting the toe portion of the last consists of a block, 2l, which is con- .nected by a tongue, 22, and pintle 23 with the pin ll. An outwardly projecting iiexible shield or curved spring-plate, 24, is secured at the middle of one end to the block 21, and its free sides are received between oblique lugs or adjustable plates These plates are fitted on a right-and-left-hand screw, 26, and are guided in' their movement by apin, 27, upon which they can slide. By means of the screw the springplate 24 can bc expanded or contracted, to permit the toe portion of different-sized lasts to be clamped between the same. A padded button or screw, 28, fitted to the block 21 can be adjusted to suit the size of the last. is secured directly on the end of one of the pins ll, the latter entering a hole in the last provided forsuch purpose. Horizontal guideways 29, arranged atthe sides of the headplate 3, receive adjustable blocks 30, carrying each an outwardly-projecting post, 31, as is shown in Fig. 2. These posts are made hollow, and have screw-stems 32, set-screws 33, and nuts 34, of the same construction as has been described in connection with the posts 9. These screw-stems 32 carry pivoted blocks 35 at theirouter ends, through which move the arms 36, carrying the side lasting-jaws.

It should be observed that the various movable blocks upon which the above-described posts are mounted are adjusted in their guideways by means of screw-shafts 37, having their bearings in the frame l and entering screwsockets in the blocks,

The side lasting-jaws (fully illustrated in the detail, Fig. 4) consist of the angular plate or holder 38, the ,block 39, and the jaw portion proper, (marked 40.) The part 38 has asocket, 38, for making the connection with the arm 36, a screw or other device serving to hold these parts together. 1n one of the walls of the part 38 are made vertical slots 38, which receive screws 4l, that project into screwsockets in the block 39, and serve to hold it firmly upon the part 38. The block 39 has lugs or projections 39n formed thereon, and at its top and bottom it carries two narrow plates, 42, which project beyond the face ofthe block and have enlargements 42, with oblique grooves 42b made therein. The narrow strip of steel 40, which constitutes the surface that seizes the upper and turns it down upon the insole, is provided with apertured projections The heel portion of the lastY IIO insole is shown in Figs. 3 and 6.

40, which tit upon the projections 39, and are secured thereto and to the body of the block by rivets or screws. Projections 40b at the ends oi' the strip 40 are fitted in rear of the enlargements 42, so as to bring the ends of said strip in line with the oblique grooves 421 In practice it is the intention to use blocks 39 and strips 40 of different sizes and lengths, according to thekind of work to be performed, and it is apparent that the necessary changes can be made without removing the holders 38 from the arms 36. This is due to the fact that the presence of the slots 38d in the part 38 will allow the screws 4l to be shifted up and down to engage with the screwopenings in blocks 39, varying in length or size. Furthermore, the strip 40 is also attached to the block 39 in such a way that it can be readily removed and replaced by a new one when it becomes broken or is notadapted to the particular kind of last to be operated upon.

The device located at the heel and toe portions of the last for operating upon the upper at these points and turning it down upon the lt consists of a U-shaped spring arm or piece of wire, 45, the middle portion of which is iitted Vin a p small plate or holder, 46, while its free ends are entered into the oblique recesses 42Fj of the plates 42 on the side lasting-jaws. During the lasting operation these heel and toe lasting devices receive a positive sliding movement for causing them to glide upon the upper and turn thc same upon the insole, and simultaneonsly with such positive sliding movement the side jaws will, by virtue of their connection with the end jaws, cause a contraction of their spring-arms and cause the latter to act in unison with the side jaws. By such operation it is evident that a continuous or unbroken line of engaging or contact surfaces exists all around the upper, and the latter is thus turned smoothly and uniformly upon the insole.

The mechanism for operating the Various lasting -jaws consists of the hand-lever 46 which is mounted on a horizontal axis having its bearings in the head plate 3, and in a bracket, 47, fixed to the rear ot" the latter. This axis carries a disk, 48, in which are made four scroll-shaped or curved slots, 48, which receive lugs or projections 49 on a corresponding number of slide-bars, 49, the movement of which is guided by suitable supporting-brackets, 3b. These slide-bars 49 communicate motion to horizontal levers 50, which extend through slots inthe head-plate 3, and are fulcrumed in brackets 50 on the front side of the latter. The levers 50 are connected with the arms 36, carrying the respective lasting- 6o jaws, and hence it is evident that a proper manipulation ofthe single hand-lever 46 will,

through the intervention of the slotted disk,

slide-bars, and co-operating devices, cause the lasting-jaws to be moved simultaneously up to their work or away from the same. Since it is necessary to vary the degree of movement of the lasting-jaws to suit the requirements ot' the work, or the size of thelast or lasting-jaws, j

we provide an adjustable connection between the levers 50 and bars 36. I

Referring specially to thc detail, Fig. 12,` it will be seen that the bar 36 is slotted longitudinally for the reception of the end of the -lever 50, and likewise, as is seen, thisend in Fig. 12. Said lever is slotted and receives a transverse pin, 5l, carried by an adjustableA plate, 52. This plate is adj ustab] y fitted on the bar 36, so that it can be moved back and forth thereon, and it is combined witha clamping bolt or screw, 53, passing through the slot in the bar 36, and having a set-nut on under side of the latter. By loosening the bolt 53 the latter can be moved or adjusted in the slot of the bar 36 to suit the changed position of the lasting-jaw, due to the adjustment of its supporting-stem in the post 3l.

It is obvious that by providing the plate 52 and its adj uncts in connection with the slotted bar and lever the necessary adjustments of the latter can be quickly and easily made in the most exact manner.

The devices above described are directly concernedrin theV operation of turning down the edges of the upper upon the insole placed on the last; and before entering into a dcscription of the devices for stretching the upper on the last, in order to permit its edges to be properly seized by the lasting-jaws, it is necessary to mention other devices mounted upon the head-plate 3 and co-operating with the lasting devices. j

In order to hold the last firmly in position while-the operation of stretching the upper is taking place, we provide the curved arms or goose-necks 55, which are fulcrumed upon the IOO IOS

posts 9, and have beaks 55I bearing, respectively, upon the toe and heel portions ofpthe last, or, more precisely speaking, upon the in.- sole placed on the last. These arms 55 are furcated and extend on opposite sides of the posts 9, so as not to interfere with the movement of the arms 36 of the 'heel and toc lasting jaws, which, as is shown in Fig. 3, pass through the furcated or open portions of said arms 55.

The heel portion of each arm 55 beyond the fulcrum-point carries a vibrating block, 55d, which is hung upon a pin, 55e, and to this block is jointed a link, 56, connected at its other end with the short arm of an elbow-lever,

57. These levers are mounted upon the posts 9, and by their manipulation the curved arms or goosenecks 55 are turned on their fulcrums and swung toward or away from the last, according to the direction in which the levers are moved. Vhen the arms 55 are bearing upon the last to hold it in position against the pull of the stretching devices, the levers 57 are in such positions against the head-plate 3 that the rm retention of the arms is insured. A simple outward pull upon the levers,-however, will, through the intervention of the links and vibrating blocks, cause the arms 55 to be swung away from the last. XVe combine with the arm 55, operating upon the toe portion of the last, means for holding the customary boxing in position during the operation of stretching the upper.

As seen in Figs. lt to 16, inclusive, a sliding block, 60, mounted on the `arm 55, has a slot, 60, for the passage ofguide-pins 6l, which serve as a limit or detlne the degree of movement of said block between the bifurcations or branches of the' beak portieri of the arm 55. This block is hollowed out on its inner side and receives a pivoted dog, 62. one end of which terminatesin a presser-foot, 62, adapted to glide over the boxing-strip and lilold the same. This dog 62 is hung upon a pivot, so that it can easily glide over the insole without catching the same, and it has a spring-encircled stem, G3, playing in an opening of the block 60, for holding it in a proper working position. On the outer side of the arm 55, and pivoted thereto, is located a trigger or releasing-arm, 64, which has a notch, 64, adapted to engage with a pin or lug, 60, on the block l 60 and hold the latter in a retracted state,as is seen in Fig. l5. A spiral spring, 65, connected with the block and arm 55, is the medium for projecting the block when the trigger is released, and when thus projected the presserfoot of the holding-dog slips over the boxingstrip and holds the same in position during the operation of stretching the upper and t-he beginning of the tui-.ning down ot' the latter upon the insole. Vlien the beak of the arm 55 is rst brought down upon the last or insole, the bent point of the trigger 64 comes in contactwith the insole, and is vibrated sufficiently to liberate the trigger 'from the projection on the sliding block and cause the spring 65 to project the presser-foot over the strip ol leather, f, employed for forming the box-toe. Vhen the toe-lasting device has commenced to turn the upper upon the boxing-strip and the retention ofthe same is insured, the onward movement of saidlasting device will cause it to press down the block 60 and cause its pin 60d to engage again with the notched trigger' 6l, for holding said block in its normal position. The trigger-arm terminates in a spring-tongue, 640, which bears upon an exterior shoulder on the arm 55, and serves to hold the block 60 in engagement therewith.

The mechanism for stretching the upper'and holding the same tightly stretched until such time as the lasting jaws have commenced their operation of turning the edges of the upper upon the insole is all located at one side of the machine, within easy reach of theA operator, and the various parts move horizontally or longitudinally, and not vertically, as in other machines heretofore devised.

The frame or sliding sash 5, carrying all the devices concerned in seizing and stretching the upper, is provided with top and bottom rackbars, 70, into which mesh spur-segments 7l ou a vertical shaft, 172. The latter is journaled in boxes on the fixed frame 4 and carries a horizontal hand-lever, l72,by means of which motion is communicated to the sliding frame through the intervention of the rack-bars,seg ments,and shaft. At the front ofthe sash 5,or the end nearest the lasting devices, we attach a'ixed frame` 72. A movableframc, 73,arranged in rear of the fixed frame carries two rack- `arms, 74, which pass through the fixed frame Aand move in contact with guide pins or rollers 75 on branches or elongations 72L of the fixed frame. Spurred segments 76 on a vertical shalt, 77, engage with the rack-arms 74, and by manipulating a lever, 78, mounted on shaft 77 the movable frame is moved to or from the iixed frame, for the purposehereinafter4 mentioned. The branches 72FL of the fixed frame are secured to the front vertical bar of the sash or frame 5. Horizontal arms or plates 80, also secured to this frame 5, carry at their opposite ends vertical strips 8l, `which face each other, as is shown in Fig. 2, and serve to clamp adjustable blocks 82 between the same. These blocks (specially shown in Figs. 7 and l0) have one liat face provided with a frictionspring, 82", while the other face is grooved and ts on a correspondingly-beveled strip,8l. A screwbolt, 83, passing through the plates 80,serves to bringl the strips 8l, carried by said plates, close together for firmly clamping the blocks 82 between said strips. By loosening the bolt 83 the plates 80 are sufficiently sprung apart to permit the blocks 82, with their attached devices, to be shifted up or down, the springs 82 on said blocks being sufficient to hold the blocks by friction until they are moved by hand. Each block 82 has an external screwthreaded tubular extension, 84, which is encircled by an internally-threaded sleeve, 85. Furthermore, a screw-stem,86,having a milled head, 87, and encircled by a spiral spring,88, passes through said block into the tubular extension 84E, and is received by a socketpost, 89, projecting from what may be termed a pincher-holder, 90. The latteris arranged in a horizontal plane, and the socket-post 89 projects from its rear side and enters the tubular extension of the block 82, as is clearly indicated in Fig. 7.

By turning the screw-stem 86 by means of its milled head, the socket-post is moved in or out of the tubular block-extension 84, thus providing means for causing the pinchers car- `ried by the holder 90 to be adjusted longitudinally to suit the size ofthe last. The pincher-holder 90 is a transverse bar having a slot for the reception of laterally-adj ustable blocks 91, the front ends of which terminate extended and constitute necks for the reception of locking-collars 92. f These necks projecting beyond the holder 90 are each provided with a tapering opening, in which is iitted a tapering plug, 93, having an angular outer portion for applying a key andascrewthreaded portion for locking it to the collar Q2. Each block has a screw-threaded opening for the passage f a screw, 95, which is journaled in the end of the holder 90, and has IOO IIO

in sockets 91, while their rear portions are a squared portion to permit it to be turned by a key or wrench. By loosening the taper plugs and collars 92 the pinchers carried by the blocks 91 can be adjusted laterally to suit lasts of varying width, and when the plugs are again tightened up and screwed to the collars 92 the pinchers are frmly held in their proper positions relatively to the last.

The construction of the pinchers is as follows, viz: A straight shank, 96, has a circumferentially-grooved round end portion, which is receivedin thesocket 91 of the block y 91, and is held therein by a set-screw, 91, in

such a way that said shank can have a slight laxial or rotary motion to allow the pincherjaws to conform to the curvature or contour of the last. The shank 96 is the point of/attachment of the stationary or fixed jaw 97 of the pinchers, and for this purpose the body 9S of the jaw and the shank 96 have knuckleplates for making the connection by a pintle in the manner of a rule-joint; A spring-tongue, 99, carried by the fixed jaw bears against the face of the shank 96 and holds these parts in proper alignment with each other until such time as the jaw 97 and its body portion are to yield or move inwardly to adapt themselves to the hollowcd-out or curved portions of the last. The movable jaw 100 is pivoted to an ear or lug projecting from the body of the other jaw, and it has a curved arm, 101, which extends inthe direction of the shank 96 of the fixed jaw. When the pincher-jaws are open, the parts are in the position seen in Fig. 7, and for closing the jaws we employ an arm, 102, which is pivoted at one end between ears 98d of the body of the stationary jaw. The

other end of the arm 102 projects through a slot in the arm 101, and at thejunction of the portion passing throughsaid slot and the part which is disposed between the curved arm and body of the stationary jaw we form cam or curved surfaces 102, so that a pulling force is applied to the arm 102. These camsurfaces will move in contact with the inner surface of the curved arm and close the jaws more or less,

according to the degree of movement of the arm 102. A plate-spring, 103, connected with the body of the fixed jaw and bearing upon the head of the movable jaw, serves to keep the jaws separated until they are closed by the action of the movable arm` It is to be understood that the above description relates specially to the pairs of pinchers adapted to be disposed on opposite sides of a last, as is shown in Figs. 2 and 7, or at all` points of the last where double sets of pinclr ers are to be directly opposite each other. At the toe and heel portions it is obvious that single pairs of pinchers only are required, and particularly at the toe portion we lind it necessary to use pinchers which can receive every possible form of adjustment.

The means for operating the pinchers-that is, opening the same to receive the upper, closing the same upon the latter to stretch it, and again releasing said upper-' may be described as follows, viz: On the fixed frame 72 are mounted horizontal posts 72b, which constitute the fulcrum-points of horizontal levers 110, the inner ends of which are also connected by pivoted links 111 with ears 73 on the movable frame 73. These levers are located in pairs at both sides of the machine, as is shown in Figs. 1 and 2,one lever 'being at the top of the frames and the other at the bottom, and a verticashaft, 112, is' firmly bolted to each pair of levers. This shaft 112 is encircled by a sleeve or tube, 113, which extends the entire space between each pair of levers. On these sleeves are mounted as many collars or hubs 115 as there are pinchers at the sides of the last, and rods 116, extending from these collars, are connected with the opening and closing arms ofthe pinchers, as is seen in Fig. 1. The collars 115 can be moved up and down on the sleeves 113, and are held in position by spring-pressed friction-plugs 118, bearing upon the sleeve, as seen in Fig. 22. Each collar has at one side an opening for the introduction of the plug 118 and its pressure-spring 118, this opening being closed by a screw, 117. On the other side of the collar 115 is a socket, 115,

which receives the end of the pincher-operating rod 116, the latter being swiveled in said socket by providing it with an annular groove capable of receiving a holding -screw, 120, passed through the socket 115. Each rod 116 has a milled surface, 1161, and it is made in., two parts, which are connected with each other by an ordinary turn-buckle, 121. Theportion of the rod connected with the pincher-operating arm is incapable of turning but the other portion can be rotated by means of the milled surface, and thus it is apparent that the various rods can be lengthened or shortened to conform to the adjustments given to the pincherholding devices. It will also be seen that the adjustable collars 115 on theencircling sleeve of the shaft 112 will permit the rods 116 to be moved up and down in unison with the vertical adjustment imparted to the pincher-holding devices. i

The pinchers arranged at the toe portion of the last, being in a different plane from the others, cannot be mounted on collars like the others, and for this reason we provide specially-adjustable fulcrum posts on the two templets, as is indicated by the numerals 125 and 126 in Figs. 20 and 21. The operatinglever 127 of these toe-pinchers is fitted on these fulcrum-blocks. and is, by means of a rod, 128, connected with the operating-arm which closes the jaws. The fulcrum-posts 125 and .126 are litted in slots made in the templets,

and have screw-ShanksA and clamping-nuts 129 for holding the same in the desired position.

In the operation of lasting boots and shoes it is a consideration to save as much time as possible, and to insure the ,seizure of the up- IOO IIO.

per by the pinchers whenever the latter are brought toward the -upper for such purpose. We have in the present machine embodied devices whereby the operation of the lever requirecto move Vthe pinchercarrying frame 4toward the lasting devices will also act upon the pinchers and cause the same to properly receive the edges of the upper, after which the special lever employed for closing the pinchers can be separately operated.

Referring to Figs. 1, 2, and 2", it will be seen that the vertical shaft 172, upon which l the lever 172iL is mounted, carries a horizontal disk, 130, from the under face of which projects a pin, 131. rlhis pin serves to connect the vertical shaft 172 with the lever 78, through the medium of an angle-plate, 132, tted on this last-named lever, this plate having an opening or passage, which is guarded by a spring-gate, 133. When the parts are in the position seen in Fig. l, the pin 131 has passed through the opening in the angle-plate and rests in rear of the spring-gate. Now by operating the lever 172 it is evident that the sash carrying the pinchers can be brought toward the lasting mechanism, and simultaneously with such movement the lever 78 is also vibrated to cause the pinchers to be opened ready for presentation to and reception of the edges of the upper. The pinchers are thus properly opened by one lever movement, and immediately thereafter the two levers are again disconnected by the passage of the pin 131 along the rear of the spring-gate and off at the end of the angle-plate. The lever 78 can then be manipulated for closing the pinchers upon the upper, and thereafter the stretching is performed by moving the sash and pinchers away from thelasting devices through the medium of the lever 72 and the rack and segment devices. I

Ve do not claim herein what is claimed in our application for Letters Patent, Serial No. 220,222, lcd November 29, 1886.
